LbosE-LEAE BINDER.4

Application filed March 29, 1926. .Serial No. 98,349.

The present invention is concerned with a loose leaf binding devicewhich may have a wide range of utility for binding blank leaves or forfiling either single leaves or folded letter sheets.

An object of the invention is to provide a device of this character soconstructed that the leaves will be securely retained in position withinthe folder and arranged to facilitate the insertion' or removalof theleaves when such insertion or removal is desirable.

A further object of the invention is to provide a spring pressedretaining plate for the leaves which may optionally serve as a tearingguide in the event that the device is used as a note book.

Further objects of the invention 4are to provide a loose leaf folder ofsimple, practical construction, which will be ruggeddur able andefficient in use, neat and attractive in appearance, capable of housing`letter sheets in compactly folded position, and `a binder which may bemanufactured and assembled with comparative economy.

llVith the above noted and other objects in view, the invention consistsin certain novel features of construction and combinations andarrangements of parts, as will be more fully hereinafter' set forth andpointed out in the claims. The invention may be more drawings wherein-Flg. 1 1s a plan view showing the binder in open position, and thespring pressed retaining plate folded over to act as a tearing guide fora sheet of material.

Fig. 2 is a view partly in end elevation of Fig. 1, and partly intransverse section on the line 2 2. y

While the folder of the present invention may be made of either flexibleor stiff back form, 1 prefer to use a pair of stiff covers 10 and 11connected to a stiff intermediate bach 12 by the use of strips Aofhinging material, such as the canvas strips 13 which may be pasted overboth the inner and outer faces of the backing element 12 and over theadjacent edges of the covers 10 and 11.

Backing element 12 is preferably formed with a pair of openingsreinforced by eyelets 14. An eyelet is provided adjacent each end of thebacking element 12 and the sheets of material to be filed indicated at15 are necessarily of a width less than the distance between theeyelets.

Additional eyelets 16 may be formed in the cover 11,. near the hingededge thereof pressed retaining plate 17, the free edge 18 of which mayconveniently serve as a tearing guide, as best seen in Fig. 1.y

The retaining plate is preferably of slightlly greater width than thesheets 15 which are received in the folder, and is formed at each edgewith an integral tubular guideway 19. These guideways accommodatecontractile coiled springs 20. One end of each coiled spring is anchoredto a stud member passed through the eyelets 14. As shown in the drawingsthese stud members may conveniently include heads 21 of greater diameterthan the eyelets, `and eyes 22 pro- Jectingy through the eyelets andengaged with the ends of the springs 20.' The opposite ends of thesprings 20 are hooked over lugs or ears 24 deined at the edges of plate18 by recessing the plate edges at 25 and notching them at 26.

In assembling the device, the coiled springs 2O are attached to thestuds, passed through the sleeves 19, and hooked over the lugs When itis desired to insert a letter sheet under the retaining plate 17, itismerely necessary to manually grasp the plate and pull it away from thebacking member 12, springs 20 yielding so that sufficient clearence isprovided under the plate for the insertion of a sheet.

The purpose of the eyelet 16 is to facilitate the filing ofsingle'sheets of a size slightly less than one of the covers of tht`binder. In this instance the studs will be passed through the eyelets 16and anchored to the springs 20, and the plate 17 will serve toyieldingly clamp the inner edge of single sheets (by which I mean sheetsof half the size of th'ose shown) against the cover 11, as

will be readily understood.

The principal reason for malringthe plate 17 relativelyvwide is so thatit may be used as a tearing guide as shown in Fig. 1, wherein the lineupon which one of the sheets 15 will be tornis indicated in dot anddash. The device is peculiarly elficacious as a letter lll() sheetfiler, because it willperniitthe letterheads to be readily thuinhed overand ei;- posed, and at the same time retain. all of the letter' sheetsin coinpaetly folded'condr.

lVhile have illustra ed. one of thepreferred embodiments of theinvention, vari- .lo ous changes and alterations might be made in thegeneral form and arrangement of parts described Without departing-fromthe invention. Hence l do not Wish to limit myself to the details setforth, but' shally con- I-'i sider myself at liberty to make suchchanges and alterations as fairly fall `Within the spirit and scope ofthe appended claims.

I claim: I l.
